So my teacher gave me this graph and I needed to calculate the slope of the hypothenuse or f'(0.25).
So 62/121 is positive and I can see that the slope is negative. Given this and only this information is it correct to just add the negative sign? my answer was something like:
62/121= 0.51 but we add the negative since its going downwards so its -0.51
I'm sorry if this is a dumb question but I've been searching for hours and I guess I don't know what to search for
Also, isn't it a little odd that the teacher used different coordinate systems for the sides of the triangle?
Edit:
This is a calculus class but I put the tags trigonometry since is just calculating the slope. The question was
Find f '(0.25)
